<![CDATA[Nafisah et al, 2017. Grain Yield of Rice Elite Lines Under Saline Prone Condition in Cilamaya Wetan, Karawang Subdistrict West Java. JLSO 6(1):21-32.Utilization of high yielding rice varieties tolerant to salinity is one way to maintain yield sustainability in salt affected rice area. As many as 30 elit lines and 4 varieties checks were tested in saline prone area in Muara Baru, Cilamaya Wetan sub district, Karawang, West Java. The trial was arranged in Randomized Block Design with three replications. Twenty eight old seedlings were planted in 3x4 m2 plot size with 25 cm x 25 cm planting space. Analysis variance showed two elit lines (1131-Ski-4 dan IR86385-50-2-1-B-SKI-2) yielded 5.48 dan 5.64 t/ha, respectively. These yield were significant higher than those of two popular checks planted by local farmers, i.e. Mekongga and Sintanur which yielded about 4,44 t/ha. Beside 11 lines had yield 0,5 t/ha higher than that of popular check variety.  Correlation analysis showed grain yield highly positive correlated with productive tiller number and filled grain number, while thousand grain weight highly positive correlated with plant height. Screening for salinity tolerance in seedling stage done in screen house showed that both 1131-Ski-4 dan BP14082-2b-2-5-TRT-35-2-SKI-1 consistently tolerant under salinized Yoshida solution at 12 dSm-1. These two lines are very potential for further tested in saline prone area.  ]]>

<![CDATA[Bernas et al. 2012. Bamboo Floated-cultivation Model for Upland Kangkung (Ipomoea reptans Poir.) in Tidal Lowland Area. JLSO 1(2):177-185. South Sumatra Province has a high potential of swampland for expansion of floating agriculture system. Swampland in Palembang, for instance, can be adapted for floating vegetable cultivation. The experiments on floating agricultural system have been done by using wasted plastic glass, bamboo for rice and glutinous rice with the application of Hycinth and water Fern compost. The purpose of this research was to build bamboo rafts which were suitable for growing kangkong (Ipomoea reptans). Previous rafts which contained water saturated soil for rice growing needed to be adjusted for kankong cultivation which prefer unsaturated soil. Two bamboo rafts were built using four plastic containers in bottom corners.The first raft was filled with soil plus compost (ratio 1:1) and the other was filled only with swamp soil. Kankong seeds were planted with the distance of 25 cm by 25 cm. Data were collected weekly and analysed statistically using t-test. Results showed that when the rafts were supported by two bamboos, plants were died due to excessive water. Plants grew well after the rafts were supported by plastic containers.  Composting significantly increased plant height, number of leaves, plants fresh and dried weight. Plant height treated with compost was 38 cm compared to that without compost treatment which was 28 cm. Fresh plant weight was 149 g/bunch with compost treatment and 25 g/bunch without. Thus, low fertility of swamp soil only required compost to increase nutrients content for plant growth.This research concluded that plant can be cultivated cheaply and environmentally safe in swampland. Further experiments such as replacing plastic container in raft construction and growing other vegetables on the raft were proposed.]]>

<![CDATA[Safriyaniet al, 2018. Correlation of Growth and Product Components on Integrated farming Padi-Azolla. JLSO 7(1):59-65.In order to increase the growth and production of rice plants that support sustainable agriculture can be done with the azolla application. This study aimed to evaluate the correlation of the components of growth and yield on rice-azolla production. The research was conducted on Karang Ketuan Subdistrict South Lubuklinggau II Subdistrict Lubuklinggau City from January to April 2018. This study used a randomized block consisting of K1=250 kg urea ha-1 without azolla, K2=250 kg urea ha-1+azolla 1000 kg ha-1, K3=187.5 kg urea ha-1+azolla 1000 kg ha-1, K4=125 kg urea ha-1+azolla 1000 kg ha-1, K5=62.5 kg urea ha-1+azolla1000 kg ha-1, K6=without Urea+azolla1000 kg ha-1. Data analysis used correlation and path analysis. The results showed that plant height and number of pithy grains correlated on grain weight with higher values than other growth components. Dry weight of straw and harvest index had a direct and positive effect on grain weight with cross coefficients value namely 1.086 and 0.755 representatives. Plant height and number of pithy grains could be used as an indicator of crop production.]]>

<![CDATA[Feed is a major factor in the business of laying ducks. Approximately 70% of the production is to feed. Therefore, to get optimum benefit, feed must be efficiently formulated. To efficient, feed must be balance, the content of feed nutrients must be in accordance with the needs of livestock, so the remaining nutrients out of feed is a minimum. In addition to efficient, balanced feed can also reduce environmental pollution. Waste produced from farm can be a source of contamination of water or wells, if there is no further waste management. One of the consequences of water pollution by livestock waste nitrogen levels are rising. To simplify and accelerate the balanced feed formulations required a software application. This paper aims to introduce balanced feed formulation based software. Application software consists of three main parts, namely database, data processing and results. Simulations conducted on laying ducks feed on the production period. Two types of feed used in this simulation, namely: regular feed (PB) and balanced feed (PS). Each type of feed is repeated five times. Simulation results with the feed formulation software application show significant difference between PB and PS feed. PS is better than PB. Application of balanced feed formulation can be used to support environmentally friendly farming laying ducks.]]>

<![CDATA[Suwandi et al. 2012. Application of Extract Compost Increased Yield and Suppressed the Diseases of Ratoon Rice Crop in Tidal Swamp of Banyuasin Regency. JLSO 1(2):116-122.A field study was conducted to test the effects of the biofertilizer preparations on yield and diseases of ratoon rice crop in the reclaimed tidal swamp of Telang II, Banyuasin Regency of South Sumatra. The biofertilizer were prepared either as dormant inoculant in liquid formulation or active inoculant in compost extract. Both preparations contain chitinolytic, cellulolytic and phosphate solubilizing bacterial community. The result showed that the yield of ratoon crops of Ciherang rice variety in the suboptimal land increased by 67% (923 kg/Ha) in response to single spraying of the compost extract. The ratoon sprayed with the compost extract had a lower incidence of neck blast and panicle blight and produced less empty grains compared to non-sprayed control. The application of extract compost appears to be a feasible method for increasing production of ratoon rice in tidal swamps.]]>

<![CDATA[Hikmah et al, 2017. Characterization of Agronomic Traits on Two Rainfed Rice Varieties on Several Levels of Nitrogen Fertilizers and Water Treatments. JLSO 6(2):176-184.Rainfed rice varieties are expected to increase yield on rainfed fields. This research aim was to identify various agronomic characters including yield of rainfed rice varieties. It was conducted at the Sukamandi Field Station at rainy season 2016/2017, using a split split plot design with 4 replications. Water management as the main plot with two levels (I1: irrigated and I2: rainfed). Nitrogen (N) fertilizer dosage as subplot with three levels (P1: 0 kg N/ha, P2: 60 kg N/ha, and P3: 120 kg N/ha) and varieties as subplots with two levels (V1: Inpari 39 Tadah Hujan Agritan and V2: Inpari 41 Tadah Hujan Agritan). The results showed that water treatment and N dosage on each variety gave different response on their agronomic characters, including yield. Tiller numbers per hill was strongly influenced by water management and dosage of N fertilizer. In irrigated treatment, tiller number increased linearly increasing N dosage. In rainfed,Inpari 41 Tadah Hujan Agritan reach maximum tiller number with 80 N kg/ha which more efficient than Inpari 39 Tadah Hujan Agritan with 91,97 N kg/ha. Rice yield was significant effected by N fertilizer and the genetic trait of each variety. The yield of Inpari 41 Tadah Hujan Agritan was higher than the Inpari 39 Tadah Hujan Agritan. Inpari 41 Tadah Hujan Agritan reached 5.70 t/ha GKG and Inpari 39 Tadah Hujan Agritan 4.62 t/ha.]]>
